Redstone & Target_Block behavior

The target block is a component that can produce, receive, and be energized; in addition to redirecting the redstone path. This is visible in the shape that the redstone takes, which is normally a cross, towards a linear or even corner shape. However, this might not accurately reflect the actual behavior near target blocks; and even cause differences when the target is energized and must also produce a signal by being hit with an arrow.

I'm adding some images of how to assemble a simple homemade test.
